If the manifolds have been removed, refit them with new gaskets (See Exhaust manifold gasket replacement ).
- 2. Locate the spark plug wires and remove them from the spark plugs.
- Overall, high pressure oil seals play a vital role in maintaining the efficiency and reliability of machinery and systems that operate under high pressure conditions. Without these seals, equipment would be prone to leaks, malfunctions, and reduced performance. By choosing the right seals and ensuring they are properly maintained, equipment owners can prolong the life of their machinery and keep it running smoothly.
- When it comes to replacing the C15 valve cover gasket, it is important to choose the right type of gasket for your engine
- Oil seals prevent seeping of potentially hazardous contaminants like dirt or fluid in the running machine

-50 °C to + 150 °C
Choose a seal that has the appropriate dimension needed for your application. The seal should properly fit the space between the stationary and rotating parts.
Over time, piston oil seals may wear out or become damaged due to normal wear and tear, extreme temperatures, or poor maintenance practices. When this happens, oil leakage can occur, leading to decreased engine performance and potential damage to the engine.

This is one of the frequent reasons for oil seal failure, and this is majorly because of the volatility of any of the elastomer’s constituents. These causative constituents may be part of the elastomer formulation, or gases that got entrapped in the elastomer during the molding process. The deceiving fact about this failure is that sometimes the oil seal won’t show any visual sign of out-gassing, however, sometimes when the out-gassing is extreme, they shrink.
The major cause of extrusion and nibbling is stress caused by high pressure. This is commonly noticed when the oil seal has a chipped or nibbled look. In fact, in some cases, the surface of the seal tends to peel on its own, which makes it have a shaved look. What the stress does is that it increases the clearance gap between the mating edges, which causes the seal to get entrapped, and then leads to severe physical damage.
